Cisco supports three first hop redundancy protocols: Gateway Load Balancing Protocol (GLBP), Hot Standby Router Protocol (HSRP), and Virtual Router Redundancy Protocol (VRRP). This article provides an overview of each of these protocols.</p>
<p><strong>GLBP</strong> is a router redundancy protocol that also provides load balancing. GLBP enables you to configure multiple routers as a GLBP group; the routers in the group receive traffic sent to a virtual IP address that is configured for the group. Each GLBP group contains an active virtual gateway (AVG) that is elected based on which router is configured with the highest priority value, or with the highest IP address if multiple routers are configured with the highest priority value. The other routers in the GLBP group are configured as primary or secondary active virtual forwarders (AVFs). Up to four primary AVFs can be configured in a GLBP group, and the primary AVFs can participate in forwarding traffic. Consequently, multiple routers can be used simultaneously to provide load balancing for the GLBP group.</p>
<p><strong>HSRP</strong> is a router redundancy protocol defined in Request for Comments (RFC) 2281. Similar to GLBP, HSRP can be used to provide backup router coverage if the primary gateway becomes unavailable. Multiple routers are assigned to an HSRP group, and the routers function as a single gateway. An HSRP group contains one active router and one standby router. The active router is the router with the highest priority value, and the standby router is the router with the second-highest priority value. Other routers in the HSRP group are in the listen state. If the active router fails, the standby router assumes the active router role and a new standby router is elected.</p>
<p><strong>VRRP</strong> is another router redundancy protocol supported by Cisco. Routers are assigned to a VRRP group, and the group functions as a single gateway for clients. A VRRP group has one master router, which is the router with the highest priority value. All other routers in the VRRP group are backup routers. A virtual Media Access Control (MAC) address is used to identify the VRRP group to clients. The virtual MAC address for VRRP groups is in the form of 0000.5e00.01xx, where xx is a hexadecimal value identifying the VRRP group number. For example, VRRP Group 1 would be identified by the virtual MAC address 0000.5e00.0101.</p>

To begin this process, Cisco ordered a Job Task Analysis (JTA) to discover what the marketplace really expects from a CCNP certified professional. The participants in the JTA included subject matter experts from all over the world.<br><br>The results of the JTA indicate that it is time for the CCNP to get back to the basics of routing and switching and also bring back troubleshooting. Overall, the marketplace would like the CCNP professional to be a more a self-sufficient and freethinking network engineer. The IT professionals surveyed indicated that the CCNP job role would include three items:</p>
<ul>
<li>planning</li>
<li>network maintenance</li>
<li>troubleshooting</li>
</ul>
<p>Cisco developed the new program around several goals, including:</p>
<ul>
<li>to better align the <a href="http://www.boson.com/certification/ccnp" target="_blank">CCNP certification</a> to the job roles</li>
<li>to better prepare the CCNP for the <a href="http://www.boson.com/certification/ccie" target="_blank">CCIE Routing and Switching certification</a></li>
<li>to focus on core technologies while delving deeper into complex routing and switching solutions</li>
<li>to reduce the emphasis on deep knowledge of advanced features</li>
<li>to provide more focus on security</li>
</ul>
<p>To meet these goals, the three new classes have been developed: <a href="http://www.boson.com/practice-exam/642-902-cisco-route-practice-exam" target="_blank">ROUTE</a>, <a href="http://www.boson.com/practice-exam/642-813-cisco-switch-practice-exam" target="_blank">SWITCH</a> and <a href="http://www.boson.com/practice-exam/642-832-cisco-tshoot-practice-exam" target="_blank">TSHOOT</a>. Three corresponding tests will follow shortly. ROUTE and SWITCH replace BSCI and BCMSN, and TSHOOT is an entirely new class. The ISCW and ONT classes have been removed. Specialized technologies such as wireless, voice and IPSec have been removed. No order of classes is enforced, however it is strongly recommended that ROUTE and SWITCH be taken prior to TSHOOT.</p>
<p>If you have already begun your journey to CCNP, there is no need to worry (yet). There are many scenarios where tests you have already passed can be combined with the new test to attain CCNP certification. The old exams will continue to be available until July 31, 2010. Also, if you will need to pass BSCI or BCMSN for other certifications, such as <a href="http://www.boson.com/certification/ccip" target="_blank">CCIP</a> and <a href="http://www.boson.com/certification/ccdp" target="_blank">CCDP</a>, ROUTE and SWITCH will count towards those certifications.</p>
<p>The Instructor team at Boson had the privilege of participating in the Alpha classes for ROUTE, SWITCH and TSHOOT. It was an amazing experience to go through the process of analyzing every slide and every lab instruction to make these classes what they are today. Many new features were added to aid in the learning process, such as lab debriefs, tear out topology maps and job aids in the lab book. We hope that you’ll agree that these classes have reached a new level of quality and technical accuracy, and we look forward to integrating these classes into our <a href="http://www.boson.com/boson-training" target="_blank">Bootcamp</a> program, as well as delivering them as individual one-week classes.</p>
